ROTARY MOTOR.

Specification of Letters Patent Patented June 15, 1909.

Application led December 6, 1907. A Serial No. 405,427.

To all whom it may concern.

Be it known that I, CORNELIUs R. Woricm'r, a citizen of the UnitedStates, residing at McLouth, in the county of Jefferson and State ofKansas, have invented certain new and useful Improvements in RotaryMotors,

of which the following is a specification.

This invention relates to rotary motors, and my object is to produce amotor of this character which Will o crate eiliciently and reliably and'which is ot simple, strong, durable. compact and inexpensiveconstruction.

With this general object in view andothers as hereinafter' a ppear, theinvention consists in certain novel and peculiar features ofconstruction and organization as hereinafter described and claimed; andin order that it Imay be fully understood reference is to be had to theaccompanying drawings in which- Figure l, is a central vertical sectiontaken on the line l-I offFig` 2. Fig. 2, is a section on the .line lI-Ilof Fig. 1. FignB, is a Section on the line III-III of Fig. 1. Fig. 4J isan enlarged section on the line IV-IV of Fig. 3. Fig. 5, is an enlargedsection on the line V-V of Fig. 3.

In the said drawings, 1 indicates the bottoni and 2 bearing standards ofa suitable stationary framework, the upper ends of the standards inconjunction wlth bearing caps 3fm-min sup orts for rigidly holding tieliorizonta shatll, L1, provided at one end with a longitudinal bore 5terminating in an openinfr t5, said bore and opening forming the in etport of the motor, as hereinafter appears. -Tlie shaft is also providedwith an opening 7 communicating with the longitudinal bore 8, saidopening and bore forming the exhaust port, and midway between theopenings G and the shaft is provided with a crank 9 which preferablyprojects vertically upward.

4 10 indicates a wheel which forms at once the ily and belt orpower-transmission Wheel and is arranged centrally between the bearingstandards and is provided with a dlametrically arranged cylinder 11,which cylinder may be cast integral with the Wheel as shown or securedrigidly thereto in any suitable manner. Midway its length and at rightangles to the shaft the cylinder is provided ivith a pair' of openings:12, and the ends of the cylinder are preferablv closed by screw plugs orheads 13.

14 and 15 indicate alined radial passages in the wall of the cylinderand communieating with the same at its outer ends, said passages beingadapted once in each rcvolu tion to alternately communicate With theinlet port opening 6 to Conduct steam to the interior of the cylinder.

1G indicates a passage in the Wall of the cylinder' and communicatingwith the interior of the latter at its outer end and at its inner endwith an extension 17 substantially paralleling the shaft and extendingrearwardly with respect to the direction of rotation of the wheel. V

18 indicates a passage in the Wall of the cylinder' arrangeddiametrically opposite and alined with passage 16 and communicating withthe cylinder at its opposite end, the inner end of passage 18 beingprovided With an extension 19 which like extension 17 extends rearwardlywith respect to the direction of rotation of the wheel, the passage 16with its extension 17 and the passage 18 with its extension 19 beingadapted to alternately register with discharge port opening 4' for thepurpose of conducting theexhaust steam from the cylinder.

20 indicates hub portions projecting from opposite sides of the cylinderand engaging the inner sides of the bearings and 2l are spring ringswithin said hubs and forming slteafln tight joints between the same andthe s 1a t..

inder and forming 1n conjunction with pack 22 are inwardly projectinghubs of the cyling glands 23 and packing 24 stullino hoxcsto establish asteam tight joint with the shaft.

25 and 2G are pistons fitting within the cylinder at opposite sides ofthe shaft and connected together by tie rods 2, and 2S n link pivotallyconnecting the crank of the shaft with one of said pistons.

ln practice assuming that the parts are in the position shown and thatsteam is employed for operating the motor, said steam passes throughbore 5 and into passage lil; (see Fig. el) and is discharged by thelatter into the cylinder outward of piston 25, it being noted byreference to Fig. 5 th at the cxhaust passage 16 of the cylinder' 1s 1nengagement al the same moment with the exhaust port of the shaft. As thesteam thus enters one end and exhausts from the other of thecyli1'1der,'it forces piston 25 inwardly and the latter forces piston 26outwardly, thc last of these actions being to cause link 2S: to

`16 moved inwardly and s wing in the direction indicated by thecontiguous arrow Fig. 1, Withcrank 9 as the axis of movement, the wheeland cylinder at the same time rotating in the same direction with theshaft 4 as the axis of movement. As a result of the rotation of thecrank around an axis dis osed out of alinement with that of the cylinderand wheel the latter are caused to rotate as ex lained. By the 10 timethe wheel has rotate sufliciently to cause the passa 14 to move from theposition shown iii illl to the position shown-in dotted lines Fig. 4,which is something in excess of ninety degrees, the piston 25 has iston26 outwardly something in excess o o'ne-fourth of their full stroke.During this movement passage 16 is in communication with the exhaustport of the shaft and by reason of its exten- 20 sion 17 continues inengagement with said exhaust port until the wheel has made a full halfrevolution, at which time the pistons and 26 have reached the inner andouter ends of their strokes, respectively, it being under- 25 stood thatthe pistons are operated under e'xpansion of the steam outward of piston25 until passage 14 has attained the osition shown b passage 15 in fulllines Fig. 4, it being 1 ewise understood that' the last.- 30 namedpassage has at such time attained the position shown by passage 14 in:full lines, same figure, it being also understood that as passage 15comes into communication with the inlet port and passage 18 with the ex,

36 haust port, steam passes from the firstnamed passage into thecylinder outward of piston 26 and escapes from the cylinder throughpassage 18 to the exhaust port o't' the shaft. The result of this cation'reverses 40 the movement of the pistons and causes the wheel with themomentum already acquiri to start on its second half revolution, Afterpassage 15 passes out of engagement with the inlet port. the steamalready discharged into the cylinder tlirouffh said passage 15 continuesthe operation described, by expansion. Then the reverse movement of thepistons is ended the wheel has made one complete revolution and thus thesteam.. is

again automatically discharged from the 1nle't port into the cylinderoutnardof piston 25 and the actions already described are re-` peatedagain and again as long as the motor 1s in operation.

If desired the motor may be used an explosiv motor or gps engine, anysuitable equipment, not shown being employed to produce alternateexplosions outward of the pistons. It will be noticed by reference tothe dotted lines in Fig. 1 which indicate the position of the cylinderand the pistons after the same have turned a distance corresponding tothat indicated by the dotted lines Fig. 4, that the openingsV 12 areprovided in the cylinder to accommodate the crank 9 thou h it will beunderstood that by making t e cylinder larger in proportion the necessitof providing said openings would be avoide From the above description itwill be apparent that I have produced a rotary motor possessing thefeatures of advantage enumerated as desirable and I wish it to heunderstood that I do not desire to ,be limited to the exact details ofconstruction shown and described, for obvious modifications will occurto a person sliilledin the art.

' Having thus described the invention what I claim as new and desire tosecure by Letters-Patent, is

The improved rotary motor herein described and Vshown comprisingsupporting standards, a horizontal shaft secured rigidl on saidstandards and provided in its encils with longitudinal bores havinglateral ports at their limer ends, the shaft being further Vprovidedwith a crank between said longitudinal bores, a wheel disposed between tie standards and arranged concentrically around the shaft, a cylinderdisposed dianietrically within the wheel, the cylinder being rovided inits opposite walls with pairs of a ined radial assages adapted toregister at their inner en s with the ports at the ends of the bores inthe shaft and communicating at their outer ends with the interior of thecylinder, the said passages forming the exhaust pair being extended inopposite direc tions partly around the shaft, pistonsl fitter in thecylinder at opposite sides of the shaft, tie rods connecting saidpistons, and a link connecting one of the pistons with the crank of theshaft.

ln testimony whereof I aiiix my signature, in the presence of twowitnesses.
